Whenever I try to upload a world to my realm, under 5 gigs it says the level export starts, and then it finishes and says it was successful, half a second later it says an error has occurred. After this I am unable to close/play/reset/download or do anything on the realm and it seems to last for a couple days, the problem is on both mobile and console and it seems to only break when you select "play on realm" from the world edit or "replace world" from the realm edit, replacing with regular backups from the backups section seem fine.
